    We have a machine at work that just grinds out the pattern on the board.
    The result is not as polished looking as the ones from those board houses though.
    And you cant do stuff like make multi layer boards and they don't have the nice
    solder coating already on all the pads.

    I like the red colored boards the best smile.gif

    It's the wrong type of ink for making PCBs.

    ^ Spectrum Engineering sells mod kits for cd printers that use resist ink...· Still requires two passes for best results however.· Nonetheless, I see this method becoming more popular and easier to use in the near future.

    The best ink for making PCBs is UV cured directly after application. It needs a very expensive print head, though.

    While I do not·doubt uv ink would be preferrable, they seem to get very nice results from the inkjet method above.· The biggest limitation seems to be the 3.5 x 2.5 board size.

    I've had hit & miss results using iron-on methods.· The best seems to be the photosensitive boards, but it takes a few attempts to get the 'feel' for exposure timing.

    I'm looking forward to improved inkjet methods.· I'm sure they'll come up with something.

    Just a minor tip when using the transparency method:

    Put the transparency over the photoresist board, then lay a sheet of clear plexiglass over that. This ensures that the transparency is perfectly flat over the board, and no UV light can "creep" in under the artwork.

    Are all forms of plexiglass transparent to UV?

    To my knowledge yes. But they can be coated with uv filter easily.

    great stuff guys thank you. Phil I will take you up on that if you have the time I would eventually like to have a fab house make my more complicated stuff but for some very quick small runs maybe 2-3 boards single sided mostly I would like to have the ability to quickly crank somehting out.

    @Vaati: I managed to get one of RipoffShack's board kits before they discontinued them. They are better then useing the boards they sell, but not that great. I recently found this interesting site on the subject.

    I've not made a PCB myself since I was at school and drew them manually with a Dalo pen (back when Noah was still in short pants). I ordered one of those kits yesterday.

    Given I'm a total newbie when it comes to producing PCB's it's going to be interesting to see how well it works. I'll let you know [noparse]:)[/noparse]

    lt's not particularly silly, is it?

    Agent420 I just ordered the kit for $65 dollars I hope that is everything I need . too bad it only does such a small board but for now I just want to see how it works I don't have one of those printers but they should be cheap enough
    have you used this kit????? Do you think it will be able to do bigger boards in the future?
    I am not clear on what exactly is worth the 65 dollars I wonder if you have to use the template they give you or if you could just tape the board down

    I'd be very interested to hear that. It looks like a pretty neat kit. Sounds like getting the laminator with it is the way to go though.

    It is odd that the laminator comes seperate. I have not ordered one so I do not know what to expect.
